JAMES JORDAN, OF LOWELL, IIASSACHUSETTS.

WRENCH.

Application filed November 16, 1921. Serial No. 515,667.

To all whom it may conce n:

Be itknown that I, JAMES JORDAN, a subject of the King of Great Britain,and a resident of Lowell, in the county oflitliddle 5 sexandCominonwealth of Massachusetts, and. whose post-ofiiceaddressis #228llloody St, have invented certain new and useful Improvements inlVrenches, off which the following is a specification.

This invention relates to a wrench which, while capable of use as amonkey wrench, is particularly adapted for use as a. pipe wrench, or inplace of pliers.

An object ofthe invention is to produce a wrench of this class thatpartakes somewhat of the form of pliers and is of especial utility inconnection with wagon body or automobile work, where oftentimes the nutor pipe to beoperated upon is located in 0 an almost inaccessibleposition which could not be reached by the ordinary wrench.

A further object of the invention is to produce a wrench the jaws ofwhich may be adjusted to approximately the opening required, andpreferably slightly more, for

the device to be operated upon, and there after one of the jaws may bemoved toward the other ina positive manner to grip the device. i 1

Another object being to provide a wrench thatdoes not require jawadjustment for each size pipe or nut. but which iscapable otoperating onseveral sizes for eacl'i adj net- I ment.

It is also an object of this invention to provide a wrench which is soarranged as to afford the greatest amount of aw closing leverage, andconsequently power, when J large nuts or pipes are to be operated upon.I

It is a further object of this invention to so arrange the adjustment ofthe jaw closing leverage that if required thev greatest leverage andconsequently power may be applied to the smallest or intermediate sizednuts or pipes, or jaw adjustment may be made, so that the device may beheld from rotation betweenthe aws without crushing tendency beingapplied thereto.

It is anl object of the invention to provide a wrenchhaving the abovecharacteristics, which is simple in construction, powerful in efi'ect,and as readily manipulated as pliers. To the attainment ofthe aboveobjects the invention consists in certain novel features of constructionand arrangement of parts which will be fully understood from adescription of the drawings and the claims hereinafter given.

Of the drawings:

Figure 1 represents in side elevation the improved wrench as it wouldappear when about to be applied to a pipe or nut.

Figure 2 a View similar to Figure 1 but showing the wrench as applied toa pipe shown by dotted lines.

Figure 8 a section onthe line 3-3 Fig ure 1.

Figure 4: a section on the line 4-4; Figure 1.

Figure 5a vertical longitudinal section through a portion of the wrenchas shown in Figure 1.

Like characters represent like parts throughout the several figures ofthe drawings.

Referring to the drawings:

The shank 10 has at one end thereof a jaw 11 and at the other end a handgrip 12. Adjacent the jaw 11 the shank is broached as at 13 to receiveslidingly therein a link 14 adapted to be held relatively to the shankby means of the bolt like member 15'having the toothed end 16 adapted toengage teeth 17 of the link 14. The bolt 15 may be held in place by aplate 15 secured by a screw 15 to the shank 10, said plate being forkedto straddle the link 14 and slotted as at 15 to allow movement of thefinger piece 19. The said. bolt being normally held in eugagement withsaid link by means oi the spring 18 and. disengaged tl'ierei rom bymeans of the finger piece 19. At its upper end the link has a jaw 20pivoted thereto at 21, said jaw having a tail like extension 22 with aslightly pointed end 23. The jaws 11 and 20 while shown as toothed andthe gripping portion converging toward the case the adjustablelink 14:may be dispensed said jaws 11 and a pin is provided at thelower end ofsaid linkso that it cannot be drawn through the slot 13. The aw closingmeans herein employed is one capable of exerting great power which maybe in the direction of'arrow A Figure 1,

To retain the carragein a given pos ition and to causethe jaws to openupon release of handle 26 a spring 30 is interposedf between thecarriage at 31. and a shoe 32 which is thereby held friction-allyagainst thetail 22causingpressure on the cam 27 which in turn istransmitted to the shank 10.

It will be readily seen that is thus held quite firn'ily but notimmovably afs, 'if desired, it may he slid along the tail to occupyvarious positions such, for instance,'as illustrated by dotted linesFigure 1. v

When operating on'a nut or pipe of small diameter and itjisniecessaryto'have the jaws come} close-together, the link 14; will first beadjusted to, approximately the right position and if necessary thecarriage 28moved toward or from the pivot 21, and thereafter the handle26 may be operated t6 grip the article. l v j If eX cessive power isrequired the initial adjustment of the link 14: will be made as beforeand the carriage 28moved away from [the pivot 21, thereby greatlyincreasing the leverage entail; 22 and consequently power at the jawthereof. j j V j Increase or deer ass of jaw closing leverage, andconsequently power may lbe obtained sliding the carriage away from or towa-rd'the plv ot 21 and for use on larger nut-sand pipes it may beadvisable or even necessary to sl de the carriage to the right to obtainthe necessary jaw opening as well I: E as, the additional leverage thusobtained. It

will be understood that the wrench may be inade n various sizes f sodesired in whlch H with andja support erected from the shank l0 toreceive the pivot 21 nov has everbeen in. use, wherein the jaw closingIt is not known" that a wrenclrof this class I devices wereshiftable toobtain variations of leverageuto,increase power or to cause wideropening of the jaws to receive larger objects and therefore it is notthe intention i iaaaso to limit this invention to the preciseconstruction and arrangement shown herein.

It is obvious that various changes-might be made in the construction andarrangement of the invention without departing from the spirit and scopethereof.
